- High-strength durability with Rockwell C45 hardness, ensuring the set screw maintains integrity under mechanical stress.
- Secure, flush installation thanks to the headless hex drive design, ideal for applications where space is limited.
- Precision fine threading (UNF) for improved engagement and clamping force in delicate or high-vibration machinery.
- Consistent performance backed by compliance with ASME B18.3 standards, ensuring dimensional accuracy and reliability.
- Environmental and regulatory safety with RoHS 3 and REACH compliance, making it suitable for global industrial use.
Professional Applications & Engineering Value
This 0-80 UNF set screw is engineered for precision applications where space constraints and vibration resistance are critical. The headless design with a hex drive allows for flush mounting in tight assemblies, preventing interference and ensuring a clean profile. Made from black-oxide alloy steel, it offers excellent corrosion resistance, reducing maintenance needs in humid or corrosive industrial settings. The fine UNF threads with Class 3A fit provide superior grip and holding power, minimizing loosening in high-stress environments like automotive components, electronics, and machinery. Its Rockwell C45 hardness ensures it withstands repeated torque without stripping, delivering long-term reliability for B2B buyers seeking durable, compliant fasteners.
Specification Summary & Compliance
This set screw features a 0-80 UNF thread size with Class 3A thread fit for precise tolerance, a 3/16" length, and fine thread spacing to ensure secure fastening. It meets ASME B18.3 specifications for dimensional accuracy and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable industrial use.
